Generic Company Place Holder JRebel (formerly JavaRebel)

Edit-compile-test-edit-compile-test. This is the "software
development cycle" all programmers know well, from "Hello World"
onwards. JavaRebel is a JAR file which will allow you to skip
directly from "edit" to "test" while eliminating "compile" (most of
the time).

Using JavaRebel is extremely simple: Just pass an appropriate
command when you invoke your Java Virtual Machine. It took me about
30 seconds to get it working in Eclipse. Once it's there, it's
transparent--and useful. To test it, I launched an application,
then, while the application was running, added in some additional
output code to the event handler for a button. After a second or
two, I received a notice in my console window that the relevant
classes had been reloaded, and the button now executed its modified
behavior. I can foresee this saving me a tremendous amount of
debugging time. Even a few minutes a day saved re-launching apps
adds up, over a year, to hours or even days of productivity,
depending on re-deployment time after minor edits.

There are a few changes it can't handle--you can't change class
hierarchy or implement new interfaces, for example, but it's
unlikely you'd be making changes like that during a standard
edit-compile-test cycle. There is also a risk factor; if the app
you're working on is "live," and you are careless with your
configuration, you could introduce new bugs into running code.
However, that's a user error and hardly the fault of the
program.

The trial version lasts for 30 days and prints a message in the
console window when run. This should be long enough to determine if
the utility provided is worth it.

Note: This file comes in two licenses, Personal
and Corporate. The license price shown here is for the Personal
version. Older versions of Java may run on certain system
configurations running older versions of Windows than those listed
here. Check java.sun.com for full compatibility information.
